This invention relates to improvements in coke oven construction and aims to provide a structure of improved design so arranged that the gas and air regenerators are located substantially in vertical alignment. The design is such that the c oke chambers are located between heating walls having combustion flues therein. The heating walls are sustained by supporting walls located in vertical alignment therewith, these supporting walls having ducts therein for conveying gas and air from the respective regenerators. The regenerators are located one over the vother between the supporting walls and a' duct,

for carrying the incoming gas or outgoing spent products of combustion, is provided which extends the entire length of the regenerators and to the outer faces of the structure. This duct permits lof ready accessto the division wall between the gas and air regenerators for inspection or sealing. In order that the invention may be fully .understood a preferred embodiment thereof is illustrated in the accompanying drawings forming part of this specification.

In the drawingsp Fig. 1 is a transverse section through the coke oven the section being taken through a coking chamber and the regenerators lying below it;

Fig. 2 is a similar sectionin a plane parallel to the plane of Fig.v 1 but taken through the heating walls and supporting walls Fig. 3 is a staggered section taken approximately on the line 3-3 of Fig. 1;

Fig. 4 is an elevation view from the left side of Fig. l;

Fig. 5 is a sectional elevation taken on the line 5 5 of Figs. 1 and 3';

Fig. 6 is a similar sectional view taken on the line 6-6 of Figs. 1 and 3;

Fig. 7 is an enlargeddetail view of the lower portion of Fig. 5.y

Referring in detail to the drawings l()l represents the coke oven as a whole which is supported on a foundation 12 in which flues 14 and 16 are provided for carrying off the 'waste gases to a suitable stacljn'ot shown.

Gas and air regenerator chambers 18`and 20 are provided which as` shown are disposed Lwalls 22.

vertical alignment withV heating walls 26. ,V

The lower portions of the supporting walls 22 between the air regenerator-s, as most clearly shown in Fig. 7, may be greater thickness than the portions of saidsupporting walls between the gas regenerators. walls 26 enclose the oven chambers 28 which are adapted to receive the material. to be coked. These oven chambers are closed at theiropposite ends by suitable doors 30 of the usual construction.

'Between each gas regenerator 18 and its companion airY regenerator 20 we provid-e a duct 32 ywhich extends substantially the full length of the regenerators. Over the top of each air regenerator isa partition wall 34 formed of flat bricks which are supported on the corbeled supporting bricks 36 forming the upper parts of each air regenerator. This -ilat partition wall 34 can be sealed tight by placing over the joint-s pulveriz'ed material of sufficient nenes's, a suitable material being finely ground fine clay or silica cement. Over the partition wall 34 we preferably place a layer of insulating brick material as indi- The luiating p cated at 35. This'material is placed so as to-- provide channelsfor holding the fine sealing material 37 above the joints of the division wall. v l Y Air ducts`38 are formed in the supporting walls' 22 and these ducts for the greaterpart of their length coincide with the center line of 'said supporting walls. Each duct 38 has at its lower end a flared Vmouth 40 which opens into one of the air regenerator chambers 20. The ducts 38 at their upper ends open into the combustion iues 40 forined'in the heating walls" 26. Also opening into each combustion `flue 40 there is a duct 42 located substantially centrally of supporting wall and having a flaring mouth 44 which opens into a respective gasregenerator 18.

The air'and gas ducts 38 and 42 respectively are so arranged that alternate combustion chambers 40 communicate with the same respective gas regenerator. Similarly alterbetween the members of a for said heating walls below the same having up-take and down-,take ducts therein for supplying gas and air to and taking combustion products from said combustion flues at intervals along the lengths of vsaid heating walls, a gas regenerator and an air regenerator in superposed relation to each other between each two of the adjacentV supporting walls and each of the regenerators communicating with one of said ducts.

2. The coke oven structure of claim l wherein the up-take and down-take -duets in each of the supporting walls are formedsubstantially along a vertical plane in and median and longitudinal of the wall and provided With laterally extending mouths opening into part of said regenerators.

3. The coke oven structure of claim 1 wherein the up-take and down-take ducts in said supporting walls are provided with laterally extending mouths opening into said regenerators and a pair of gas gun conduits formed in the upper portions of each of said supporting walls, the members of a pair of said gas gun conduits lying on different sides `of each of the up-take and down-take ducts in the wall, the said gas gun conduits communicatinor with said combustion ues.

4. The coke oven structure of claim l wherein the up-tak-e and down-take ducts in each of the supporting walls are formed substantially along a vertical plane in and median and longitudinal of the wall and provided with laterally extending mouths opening into part of said regenerators and a pair of gas gun conduits formed in the upper portions of each of said supporting walls and communicating with the combustion iues in the heating wall thereabove, one gas gun conduit of each of the pairs lying on a diii'erent side of one of said ducts from its mate and buckstays for each of said supporting walls and said heating walls at the lateral ends thereof, each of said buckstays lying pair of said gas gun conduits. y Y

5. The coke oven structure of claim 1 wherein the lower portion of each of the supporting walls is thicker than an upper portion thereof between the upper regenerators. In witness whereof, we have hereunto signed our names.
